5-Oxa-13,14-didehydro-11-deoxy-PGF1 α compounds

ABSTRACT

This invention comprises certain analogs of the prostaglandins in which the double bond between C-13 and C-14 is replaced by a triple bond. Also provided in this invention, are novel chemical processes and novel chemical intermediates useful in the preparation of the above prostaglandin analogs. These prostaglandin analogs exhibit prostaglandin-like activity, and are accordingly useful for the same pharmacological purposes as the prostaglandins. Among these purposes are blood pressure lowering, labor induction at term, reproductive-cycle regulation, gastric antisecretory action, and the like.

The present application is a divisional application of Ser. No. 657,740, filed Feb. 13, 1976, now pending issuance as a U.S. patent.

The present invention relates to prostaglandin analogs, for which the essential material constituting disclosure therefor is incorporated by reference here from Ser.
